JOHN GREENWOOD, OF ROCHESTER, NEW YORK.

IMPROVEMENT lN JOURNAL-BOXES FOR SHAFT-HANGERS.

Specification forming part of Letters Patent No.159,260, dated February 2, 1875; application filed October 24, 1874.

To all whom it may concern:

Be it known that I, JOHN GREENWOOD, of

the city of Rochester, in the county of Monroe of the construction and operation of the same,

reference being had to the accompanying drawings, in which Figure 1 is an end elevation, showing my improvement applied to a hanger. Fig. 2 is a longitudinal vertical section of the journalbox. Fig. 3 is a perspective view of the same. My invention relates to hangers for shafting; and consists of a box made in one piece, and constructed with lips or flanges for catchin g the drippings at the ends of the box, and with a closed chamber beneath for holding the drippings, as hereinafter described.

111 the drawings, Arepresents the box, which is supported in a forked hanger suspended from the ceiling, the connection being made by means of a bolt or pin, which passes transversely through the box beneath the bearing, as shown. The box rocks on this bolt, and is adjusted by means of a check-screw, as usual. The box A is cast in a single piece, and consists of the bearing b, through which the shaft passes; an oil-cup, 0, above it, for applying the oil; and an oil chamber or receptacle, d, below the box, for catching the drippings. In the act of casting this chamber is cored out, so as to leave the receptacle cl closed at the bottom and the sides, the only openings being formed at the ends, as shown, at f f, and at the bottom, which is filled by a plug or stopper, g, for the purposeof drawing off the oil when a quantity has collected. At the ends of the box are lips or flanges h h, projecting out some distance beyond the ends of the bearing 1), and standing upward, so as to catch the drippings from the ends of the box without escaping or running down over the sides.

The oil escapes from the ends of the box and strikes upon the lips h h, and passes through the openings ff into the chamber at, and settles to the bottom; and when the chamber is filled, the oil is drawn ofi' by removing the plug 9 from the nipple 7c.

Boxes with oil-receptacles have before been employed, but are generally open, so that dust can settle in the oil and gum it, thereby rendering it unfit for second use.

The distinctive feature of my invention is the lips or flanges h hat the ends of the box, projecting beyond the bearing portion and standin g upward, so as to catch the drippings, thereby preventing the oil from running down the sides of the box and besmearing the same. Another feature is the chamber at beneath the bearing, made closed, except at the inlet-openings f f, so that but very little dust or dirt can enter.

A hanger thus constructed can be cast in a single piece, and is, therefore, very cheap and simple.

Having thus described my invention, I do not claim, broadly, a box having a drippingchamber for catching the oil; but

What 1 claim is The box A, cast in a single piece, with the oil-cup 0, bearing 7), and oil-chamber d arranged below said bearing, and constructed with the lips h, projecting beyond the ends of the bearing, and with the opening f and the nipple 70, for receiving the plug 9, and otherwise constructed as herein shown and described, for the object specified.

In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.

JOHN GREENWOOD.
